Have ballistics findings been released, or is that also covered under the gag order?
As an aside, seems I’d read somewhere (I could be mistaken) that these grand juries are handpicked retired judges and former prosecutors - anyone know anything about that?
No.
That said, "random" selection, supervised by judges, is NOT random. A judge can dismiss any prospective grand juror, using a pretext.
Look up the story of Vic Feazell. (sp) A Grand Jury was seated for 11 months and could not get an indictment. Another one was seated and an indictment was returned in 4 days. Later after Feazell’s acquittal members of the second Grand Jury came forward and said they were threatened by IRS agents that their lives would be made miserable if they didn’t vote for an indictment.
